On continuity of maskin’s implementation result /

Abstract

This thesis displays that the seminal results of Maskin (1999) on Nash implementation are continuous with respect to a specific measure when attention is restricted to the domain of preferences representable by cardinal utility functions. Our continuity measure is associated with three modified components of Maskin’s results: epsilon-implementability, epsilon-monotonicity and epsilon-no veto power. Employing cardinal utility functions, we define epsilon-neighborhoods around Maskin’s standard components and show that his results continue to hold with this epsilon-approximation.
